Abstract
The fatigue life variation coefficients versus its base were obtained on the basis of statistic processing of titanium disks test and operation results. The lower boundaries of the D-30 and D-30KU engines’ LPC stage 1 disk life distribution in the area of fillets of dovetailed grooves were determined.
